What is the value of the expression? Enter the answer in the box.<br> 4+(8 - 7) X6-1
e-lub [12.9K]
Answer: 9

Explanation: you would use PEMDAS to solve the algebraic expression first by doing parentheses so subtract 8 and 7 which leaves you with 4 + 1 times 6-1. You would then multiply 1 into 6 which would leave you with 4 + 6 - 1 which you would then sum up 4 and 6 which leaves you with 10-1 which would give you the answer of 9

So the answer would be 9

Hope this helps!
